PRE-INSTALLATION SPECIFICATIONS
Preparing the Space
NOTE: Make sure floor under appliance is level with surrounding finished floor. Protect finished floor with masonite,
plywood, 1/8” (3 mm) pressed fiberboard, or some other suitable material before moving the appliance across it.
Electrical Requirements
To rough in the electrical outlet following the Pre-Installation Specifications. You will need a 115 Volt, 60 Hertz elec-
trical supply, with a dedicated 15 Amp fuse / circuit breaker. Also be sure to follow any local codes that apply.
The appliance comes with a three-prong grounded plug power supply cord. The appliance must be plugged into a
mating three-prong wall receptacle grounded in accordance with the National Electrical Code and local codes.
Plumbing Requirements
The unit has an automatic ice maker with a water filtration system, which operates on water pressure between 35
psi (2.4 bar) and 120 psi (8.3 bar). If the filtration system is bypassed, water pressure must be maintained between
20 psi (1.4 bar) and 120 psi (8.3 bar).
Rough in the water supply using 1/4" OD copper
tube. The water line should be routed up through the
floor within 1/2" (13 mm) from back wall and no high-
er than 3" (76 mm) off the floor. If coming through
the wall, make sure the water line is no more than 3"
(76 mm) from the floor. Regardless of the routing,
allow 3' (914 mm) excess copper tubing outside the
wall or floor for easy connection to the unit.
Locate water supply line within shaded area indicat-
ed in the Pre-Installation Specifications diagram.
Use an easily accessible shut-off valve between the
water supply and unit. Do not use self-piercing
valves. A saddle valve kit (part #4200880) is avail-
able from a Sub-Zero dealer.
It is not recommended that the appliance be con-
nected to a softened water supply. Chemicals, such
as salt from a malfunctioning softener, can damage
the ice maker and lead to poor ice quality. If a soft-
ened water supply cannot be avoided, be sure the
softener is well maintained and operating properly.
NOTE: Do not use with water that is microbiological-
ly unsafe or of unknown water quality without ade-
quate disinfection before or after the system.
Systems certified for cyst reduction may be used on
disinfected waters that may contain filterable cysts.
NOTE: Installations must meet local plumbing code
requirements.
NOTE: A reverse osmosis system can be used, if
there is constant water pressure of 20 psi (1.4 bar) to
120 psi (8.3 bar) supplied to the unit at all times. In
this application, the integrated water filtration system
must be set to bypass mode.

MOVING THE APPLIANCE
After uncrating the unit, do not discard the kickplate that
is taped to the side of the refrigerator. Do not discard
the Anti-Tip Kit or hardware, you will need them to block
the installation.
Carefully move the unit from the crate base onto an
appliance dolly. Tip to one side removing styrene pads
under unit. Tip back onto appliance dolly. Retract lev-
eling legs to their uppermost position for easy move-
ment of the unit while installing. Remember this unit is
very heavy (900lbs/408kg) and enough manpower
should be used when attempting to move this equip-
ment.
Protect the Flooring
Make sure the floor under the refrigerator is level with
the surrounding finished floor. Pushing the unit with
front leveling legs down will cause damage to the floor.
Make sure the leveling legs are in the uppermost posi-
tion prior to moving the product. Protect a finished floor
with masonite, plywood, 1/8”(3) pressed fiberboard or
some other suitable material before moving the refriger-
ator across it.
Product is very heavy (900 lbs/408kg) keep door(s)
and drawer(s) closed while moving unit and use
enough manpower to safely move unit.
Protect any finished flooring before moving the unit in
place. This Sub-Zero product is equipped with rollers,
so it can be easily moved into place. If for any reason
the unit has been laid on its back side, you must allow
the unit to stand upright for a minimum of 24 hours
before connecting power.
When using appliance dolly, make sure the strapping is
underneath the door handles and either underneath or
over the top of drawer handles. Use enclosed corner
protectors to avoid damage to stainless steel. Do not
cut corner protectors when unpacking the product.
Removing the Grille
In order to prevent damage to the grille, the top grille
assembly should be removed prior to moving the unit.
To remove the grille assembly, pull out on the bottom
edge of the grille and tilt the grille frame forward (See
Figure 2-4). Disconnect the low-voltage cable which
connects the User Displays on the grille to the
Technician Display Module, and cut the two white cable
ties which attach the network cable to the right grille
support. These cables ties should be replaced once
the unit is properly installed with the extra cable ties
provided. Remove the three 7/16" bolts from base of
the grille. Remove the screw from the upper grille area
and remove the grille assembly.

Water Filter Bypass
If choosing not to use the water filtration system, the
system can be bypassed by removing the water filter
cartridge. If done, the water supplied to the ice maker
will not be filtered and the electronically controlled water
filter monitor will be deactivated.
Lift the grille to access the water filter cartridge by
pulling out on the bottom edge of the grille, then tilt the
grille frame forward (See Figure 2-17).
Slowly rotate the water filter cartridge 1/4 turn counter-
clockwise to disengage. Gently twist until the cartridge
is free from the base, DO NOT pull (See Figure 2-18).
There will be water in the filter cartridge, so it is normal
for a small amount of water to spill out.
